3.2.1 Additional property values . When specified by the procuring
activity, the contractor shall supply data for shrinkage, dielectric
strength, dielectric constant, and volume resistivity of the bulk material
supplied to the Government.
3.3 Suitability of resin . The epoxy embedding compound shall be suitable
for application and use on electronic assemblies and individual parts. It
shall preserve the electrical properties of the equipment to which it is
applied by sealing against such environmental conditions as moisture, dirt,
fumes, fungus, or other deleterious substances which may be encountered in
the military services. It shall be capable of mechanically supporting the
part or embedded assembly and shall not require a case or other external
support after curing has been completed, though a potting container may be
used. It shall not cause deterioration of materials used in electronic
assemblies and parts.
3.4 Pot life. The compound shall have a pot life long enough so as to
produce uniform castings, free of bubbles and cracks that may affect
serviceability. The manufacturer shall furnish instructions on proper mixing
of components. When required, the procuring activity shall specify minimum
pot life (6.2).
3.5 Workmanship. The epoxy embedding compound shall be a clean
homogeneous mixture free from lumps and foreign material. The diluents and
fillers shall be thoroughly dispersed in the compound, as determined by

may be used to return the material to the homogeneous thoroughly dispersed
condition.
